I'm not a fan of trainer jets. They are not realisticly training you for anything as all other jets will fly different. I've seen a few people get a trainer and not be able to move beyond it because they got too used to it.
It depends on your flying history. Many EDF are far harder than turbine jets.
One risk you are taking with the Faggon 120 clone is it may come apart and kill your turbine. If you are going to do a trainer get one that is proven like a tornado or boomerang. Fly it like a trainer as well.
